Port forwarding allows passing external connections to computers in the internal network. Almost all routers support this type of redirection. For example, to access VNC or TightVNC server running on default ports, a router can be configured such way that TCP connections to ports and would be passed to the same ports of a particular machine with a specified private IP address typically Next, run the vncserver command to set a VNC access password, create the initial configuration files, and start a VNC server instance:.

The password must be between six and eight characters long. Passwords more than 8 characters will be truncated automatically. Users who log in with the view-only password will not be able to control the VNC instance with their mouse or keyboard.
